Display Drivers datasheet and documents for BU9798KV-E2

BU9798KV-E2

Display Drivers Overview

The BU9798KV-E2 is an LCD segment driver manufactured by ROHM Semiconductor, designed for line/frame inversion driving. It supports up to 196 segments and operates within a supply voltage range of 1.8 V to 3.6 V. The device features a 3-wire serial interface and a maximum clock frequency of 4 MHz. Packaged in a VQFP-64 format, it has a maximum power dissipation of 1 W and a maximum supply current of 130 uA. The component functions reliably across an operating temperature range from -30°C to +75°C.

Display Drivers Feature Summary

Supports Line/Frame inversion driving modes for LCD displays
Integrates a 3-wire serial interface for data communication
Includes built-in oscillation circuitry for frame frequency generation

Display Drivers Applications

Segmented LCD display drivers
Consumer electronic devices requiring low-voltage operation
Portable instrumentation with limited power budgets

Display Drivers Procurement Notes

Verify the specific suffix against official documentation, as variations may exist. Confirm that the VQFP-64 package dimensions align with your PCB layout requirements. Ensure the 1.8V to 3.6V supply voltage range matches your system's power architecture. Check humidity sensitivity levels if moisture protection is required for your assembly process.

Display Drivers Selection Notes

Select this component when a 3-wire interface is preferred over I2C or SPI protocols. It is suitable for applications requiring support for up to 196 segments without external multiplexing components. Consider the 1.8V minimum supply voltage for compatibility with modern low-power microcontrollers. Evaluate the 1W power dissipation capability against your thermal management constraints.

Display Drivers Part Context

This part belongs to the BU97981KV series of LCD drivers. It shares functional similarities with other ROHM segment drivers but is distinguished by its specific segment count and interface type. The E2 suffix typically indicates environmental compliance, such as RoHS standards, consistent with ROHM's product naming conventions.
